About Ingpuls Medical
Ingpuls Medical GmbH is a specialized company of the Ingpuls Group based in Bochum that focuses on the development and contract manufacturing of ultra-pure Nitinol (nickel-titanium shape memory alloys) for the medical technology industry. The company manufactures semi-finished products such as melts, electrodes, bars, hollow materials, stent tubes, wires, sheets and powders for additive manufacturing. The value chain begins with precise vacuum melting (VIM) and includes hot swaging, wire and tube drawing, heat treatment with shape setting, mechanical grinding and electropolishing through to CNC machining and final inspection. The alloys are characterized by an inclusion size below 5 µm and a volume fraction below 1%. Since 2024, the company has been certified to DIN EN ISO 13485. Ingpuls Medical serves the medical technology sector and, via its sales partner Kanematsu Corporation, is also active in the Chinese market.
